[R] run a script during R CMD build

[Adaikalavan Ramasamy]

Sorry, I did not read the question properly.

I believe all your functions goes in mypkg/R and your data goes into 
mypkg/data subdirectory respectively but I am no expert in this area.

If you want to reflect your data from one folder to another, you can try 
using a symbolic or soft link in *nix systems
ln -s /inst/mydata.Rdata /somewhere/mypkg/data . Not sure if it the 
symbolic link approach will work when you try to R CMD BUILD mypkg.

You might be interested in the examples in package.skeleton().

Regards, Adai
